Eat a Sheep
A lion takes 4 hours to eat one sheep, a leopard takes 5 hours and a bear takes 6. If a single sheep was thrown to them, how long would they take to devour it?
Answer
60/37 hours (about 1.6 hours). In one hour a lion eats 1/4 of a sheep, a leopard eats 1/5 and a bear 1/6. So in one hour combined they eat 1/4 + 1/5 + 1/6 sheep. Therefore one sheep will take 1 / (1/4 + 1/5 + 1/6) hours = 60/37.Hide Answer Show Answer
